Damn... Posted here so many photos of EP20 it looks like we are talking about it. I just love this glorious machine.
Better will post a photo of the Dragon FTGJ.

>>131902 -- Actually, the brochure was overflowing with clues, beginning with a word that looked like 'asynchronous'. Plus, there were block diagrams of the power system and oscillographs of the sinewave form changing with frequency.

>>131914
Well, since Polish is some kind of far relative of Russian I think I can translate other parameters (at least which aren't already obvious):
Maximum speed in service - 120 km/h,
Length by buffers - 20250-20330 mm,
Width - 3000 mm,
Height - 4325 mm,
Wheel diameter - 1250 mm,
Type of traction motors - STX500-4A or ABB AMXL450,
Starting traction effort - 310 kN,
Short-time mode (?) traction effort - 275 kN,
Maximum dynamic braking effort - 200 kN,
Maximum traction motor current - 300 A.
Also it seems like the battery is designed to feed the traction motors for short time.

And by the way... What the hell? Looks like Dragon's styling is popular in Ukraine.

>>131932
...well, technically in South Korea too because they have designed HRCS2.

> Short-time mode

If I recall correctly, this would be the maximum effort a locomotive can sustain for one hour before the traction motors become too hot.

>>131961
Often yes, but on some traction drives time which they can work safely in this mode is sacrificed in order to provide more power. Like on 2ES10. Its short-time mode lasts 15 minutes but the power increase is 100 kW (10%) per motor.

I believe that should be the case with most or all motors, though this is the first fifteen-minute rating I recall having seen mentioned anywhere.

>>131964
Well, I have also heard a half-hour mode for some Russian switchers. Of course, it is not about power, traction motors can't have more power than the amount provided by the prime mover. IIRC it is unfavorable mode of the collector motors in which they provide increased torque at low RPM which can be useful for a shunting locomotive but generate more heat than their cooling system can handle protractedly.

>>131928 [OP]
Not exactly. The discone is for shunting VHF radio communication and the wire is for mainline MF or VHF radio communication, signal for the second is usually provided by contact wires or SCI feed wires used as waveguides. But as I can see they started to refuse from the discones, dunno why exactly. Managed to take both signals in sufficient quality from the wire maybe? Not quite good at this.

I think the 2ES6 on your pic still has a separate antenna for the yard radio, namely that cone-on-a-cube thingy to the left on the cab roof.

Just out of curiosity, do they use satellites to determine location? I wonder if one of those white antenna housings protects an antenna for a GLONASS receiver.

Otherwise, if I were to hazard a guess by scaling the antenna size i'd say it's in the UHF band... maybe as high as 33cm in wavelength?

These Russian trains are fascinating. :-)

>>131953
I have already spoken of this in RZD thread.

> However, our modern signalling (KLUB-U/BLOK) maybe is based on block sections but still is fairly advanced: it can monitor up to 5 block sections ahead, the position of the locomotive is tracked using GLONASS (previously GPS) with a precision of a few meters, which allows some useful resulting features like targeting system which helps a passenger train to stop at platform more precise and effective when working in advice mode or to do it automatically if automatic driving is equipped and on, it can maintain train speed within limits and stuff like that. Almost every line with sufficient passenger train traffic is equipped with this signalling, but, as a rule, all rolling stock on such lines has appropriate onboard systems, however, ALSN/ALSM and KLUB-U/BLOK equipment is mutually compatible, but in this case only supported by the inferior system features will work.

Every KLUB-U/BLOK computer uses interactive map which contains all important points of the line including signals, platforms, speed restrictions, warnings and other stuff you need to provide to the driver or even to drive the train automatically, BLOK is able to contain also the entire track profile of the line.

>>131953
And about the antenna cap, I think the answer is on the picture above, it is probably for the denoted digital communication antenna. However GLONASS receiver is this white box on the top of the picture so maybe an antenna for it is hiding inside this little cap against the big one. Never have seen the "map" of all roof equipment of an electric locomotive, unfortunately.

Trust me to forget all abnout GLONASS's existence... (feeling very grumpy at self) After all, my smartphone has a dual-system (GPS/GLONASS) locator.

>>131898
Not a problem. Didn't think though that boobs are strictly forbidden here too, even if they are directly related to the trains and is just part of the bigger picture (literally). Anyway, it was just closest pic to the topic (not counting documentary photos with consequences of real accidents) I have found.

>>131880
Or remember not to broadcast one's dickishness to the entire train.

>>131901

I understand your intent, and I appreciate what you were trying to say, but boobs fall under "NSFW", artistic or not. I wish it was not so, even I found that picture to be tasteful, even though it is what we all gnash our teeth about.

Back to trains, eh?

I probably wouldn't be that bad, but I am pretty cold when someone gets minced by a train - largely because I do have somewhere to get to and they were inconsiderate enough to make a driver feel bad. Perhaps to my twisted amusement, some of the other passengers get really emotional about it.

Of course, we should all spare a thought for those in Tokyo every other morning.
On that note - I've always wondered why every subway station has a small tap and a stone sink at every station. Surely it couldn't be for fire fighting so I can only assume it's for filling buckets to wash off the blood. Although apparently some are labelled as drinking fountains? They could've put a lot more effort into making them easier to drink from!
(that's my sperging for the day)

>>131924
Maybe they use pressure washers to clean the platform area? You know, from substances other than blood too.

How fast they can remove the body, btw? Fast enough so the commuters can finish their journey in a bloody train?

>>131924 Wow I once said something similar and the whole board pounced on me for being cold hearted.

>>131930 -- As I recall, you worded it like it was all a joke to you.

If you want a tall tale, a mutual friend on the railway tells of a driver who had 50 or so mincings in his career to the point of earning a nickname. The one that did him in being a child slipping off a platform in an accidental circumstance.

>>131927
They pick up as many pieces as possible before washing the rest off. I think for the health and safety factor, they pretty much always pull the train out of service (and in the case of a slam on the windscreen, they pretty much have to. If the train washes in Japan are the same as here, there's an oxalic acid wash to sanitise the exterior.
There was a video of the station staff just using water buckets and splashing it off...and another of the trains just running anyway even though there was a decent bit of blood and meat on the tracks. (I'll leave finding them to you).

Cleaning up is pretty quick and in standard Japanese fashion, they almost always have the moving curtain and stretcher even if it's in pieces. That and the staple repeated shouts of abunai with warning tape to keep those too curious a reasonable distance. The big delay as I understand is in the bureaucratic part of getting the police and such to tick the boxes and say yep this wasn't a murder.
Even in Sydney the big delay is the bureaucratic part. They can clean up pretty quick.

You were at the station around the time this happened, right?

>>131945
Hah, no. That happened way after my Japan trip (which I hope to make again when I'm not broke, maybe once I graduate in 2 years' time). The closest I've been was rolling past the bits left after a girl had tried to run across a quadruple track at Hurtsville [sic] during peak hour as they had the green tarp draped over.
I wasn't far from Yokohama Station when the train stopped for that time in Japan though, albeit on the Keihin Tohoku rather than Keikyu. And every other morning on the screens you'd see notification of delays somewhere in Tokyo due to 人身事故.

Of course, I feel dirty for discussing a subject such as this. My feeling towards the deceased is largely apathy due to needing to be somewhere but even still. It does intrigue me because of how much they try to pretend it isn't a thing (although the railway here will explicitly mention if someone was killed vs an injury on the delays page).

Welcome to the funny farm! You'll find that there's a handful of us here that are professional railroaders in a few different crafts.

So you want to be a conductor, eh? Unfortunately, this very moment doesn't seem to be a terribly good time to try to hire on. The railroads are in a downswing due to traffic not meeting their expected demands. However, we can help you get started so you'll know what to do when the time comes.

Here's the thing that concerns me the most:

>Would an academic like myself hate the notion of working as a conductor?

That's a very good question. The number one thing you need to know about working for any railroad is that the vast majority of them don't have set schedules. You can and will be frequently called at any time day or night. The only restrictions are that you have to be "rested", which is federal jargon for "he's been off duty long enough". You'll often find that you'll come home, get your eight hours' "rest", get some good sleep, and then you sit around all day waiting for a call. Nothing happens until your day is gone, you're just starting to get tired again, and at the time you consider going back to bed, your employer will call you and want you to work a job that can last up to 12 hours. Repeat ad nauseum for five to ten years until you build up enough seniority to hold down a specific job that, even if the schedule is crappy, gives you a better idea of when you're going to work.

This is roughly what a scoutmaster from a neighboring troop said to me when I was 12 years old and expressed excitement at how cool his job must be as a trainmaster for NS. Any notion I had of ever working for the railroad was completely wiped out by what he had to say.

I will say that your general notion is sound. College will always be there when you want to go back, why not do something cool for a while and take a break from it?

I'm a furloughed conductor working as a track maintainer.

Finish school and don't do this. It's a fine and fun career at times, but the instability, the danger, and the hours make this a pretty undesirable lifestyle for most people. The romanticism of it is still there at parts, but it becomes a job at some point and the magic fades.

>>131937
Trainmasters are, for the most part, professional dick heads. I wonder how some of them can even sleep at night.

The railroad industry needs physics majors in the research and testing fields... So finish college dammit. Should this be the direction you consider it would help to focus on the applied classes rather than the theoretical.

Post anything man. Really blissful content. I only wish to ride the rails like you someday my friend.

Checked it out, nice, stay blessed Dirtyfam.

I made it to Tucson again and there's hippies everywhere I'm leaving

>>131809
He aint that bad, you love him and squeeze. What ever man hope that Amtrak was a good ride out of texas.

>>131874
I love sober Justin. I wish I'd filmed drunk Justin cus my god it's the most annoying mess in the world. Even Squeeze doesn't like drunk Justin and squeeze loves him. Drunk Justin; throws up, picks fights, argues about every little thing and is always in the wrong, overly aggressive, attracts all the wrong attention. It is that bad. And Amtrak was nice it had this really cool car that was just like 90% windows and people kept buying me food. The whole breaking down outside Lordsburg for 4 hours thing wasn't even bad. The having to listen to people complain about something that workers were clearly trying to fix for four hours was the only annoying thing about it

>>131874
Also Eli called and he's sending me a 200$ westy, says you can have money too if you own up to being a shit show at his house

>>131878
I know dude I'm an ignorant fucker when I get blacked out drunk I just have this thing since I was a kid if I haven't puked I'm not drunk yet but isn't everyone? I try not to get like that around people that don't drink I don't want to piss off my friends man and suck but sometimes I just get Drink and don't want t stop if that makes sense an that's when I forget and change into blacked out Justin everyone's told me about this I've been really tryin to change no malt liquor stay away from liquor and wine AA up in here but my bad you had to deal with that shit... an that sounds cool, people are crazy. Does he want me to call him or something because I already have said sorry to him too

>>131805
Road, wifi, railroad?

That's my tag. If you haven't noticed I'm online a lot. I love wifi

At JR Hokkaido, even the evacuation drills go bad!

Come to think of it... do they even have thunderbirds available in case the tunnel blacks out for a long time?

Working on a track cleaning car using these Lego erasers I found in the bargain bin at Bed Bath & Beyond. Now I've got them mounted just right so they rub on the track without creating too much resistance, I'm trying to figure out how I want to motor it up.

I'd like to do something like this where the little cart in the first picture rides underneath a large machine like this, but I'm not sure I can build it short enough to both fit the little cart AND survive the 15" radius curves.

For all of you that, at least sorta like Legos, this is a history lesson you'll get a kick out of.

Picture not related.
Maybe.
